Minor issue.
I'm on redfin and have the official wireguard client installed. After a reboot, the "key" symbol appears in the Notification bar. However in the WG client the vpntunnel is NOT up.
Simply toggleing the tunnel on/off clears the key in the Notification bar.
Both redfin and WG client are latest.
It's not even annoying, but I did wanted to mention it.
